Ok, I have a financial background and have done bookkeeping for small business. If you do not know what you are doing then you are better off paying for a bookkeeper. They really do pay for themselves in the long run. You are better off spending your time growing the business, making more money or saving money in other areas. It may take them 5 hours to do what would take your 20. Do the math, what is your time worth compared to what you pay them. Use your expertise in the right areas and bring in experts where you do not have that expertise. $25ph is very cheap for a bookkeeper, well I am assuming that you are referring to a contract rate, in fact I think too cheap.

One option you can do is bring in a bookkeeper for the short term and get them to show you how to do your books and set-up systems. It would be helpful for you to do some courses on bookkeeping and one on MYOB. Another option is moving across to Quickbooks (I prefer it), you may find it a bit easier. At the end of the day though you need to know some accounting basics to know what you are doing in the software.
